java.lang.Throwable: EventHub.removeMessages(int what = 107) is not supported before the WebViewCore is set up.

Hi,
i have tried to create a sample with this code:

```
import com.airbnb.android.airmapview.AirMapMarker;
import com.airbnb.android.airmapview.AirMapPolyline;
import com.airbnb.android.airmapview.AirMapView;
import com.airbnb.android.airmapview.DefaultAirMapViewBuilder;
import com.airbnb.android.airmapview.listeners.OnMapInitializedListener;
import com.google.android.gms.maps.model.LatLng;

import java.util.Arrays;

public class SelectMapAreaGame extends AppCompatActivity implements OnMapInitializedListener {

private AirMapView map;
private DefaultAirMapViewBuilder mapViewBuilder;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_select_map_area_game);

mapViewBuilder = new DefaultAirMapViewBuilder(this);
map = (AirMapView) findViewById(R.id.map_view);

map.setOnMapInitializedListener(this);
map.initialize(getSupportFragmentManager());

}

private void addMarker(String title, LatLng latLng, int id) {
map.addMarker(new AirMapMarker.Builder()
.id(id)
.position(latLng)
.title(title)
.iconId(R.drawable.ghost)
.build());
}

@Override public void onMapInitialized() {
System.out.println("Map onMapInitialized triggered");
final LatLng airbnbLatLng = new LatLng(37.771883, -122.405224);
addMarker("Airbnb HQ", airbnbLatLng, 1);
addMarker("Performance Bikes", new LatLng(37.773975, -122.40205), 2);
addMarker("REI", new LatLng(37.772127, -122.404411), 3);
addMarker("Mapbox", new LatLng(37.77572, -122.41354), 4);
map.animateCenterZoom(airbnbLatLng, 10);

// Add Polylines
LatLng[] latLngs = {
new LatLng(37.77977, -122.38937),
new LatLng(37.77811, -122.39160),
new LatLng(37.77787, -122.38864)};

map.addPolyline(new AirMapPolyline(Arrays.asList(latLngs), 5));

// Add Circle
map.drawCircle(new LatLng(37.78443, -122.40805), 1000);

// enable my location
map.setMyLocationEnabled(true);
}
}
```

and i have a blank view with this in the console:

```

```

how i can fix?

Start by reproducing the sample around AirMapView.initialize(), DefaultAirMapViewBuilder, and the OnMapInitializedListener callback, then compare the blank view with the Android WebView stack trace. Done means the sample displays the map and the reported initialization error no longer occurs.
